DOCBOOK-APPS: itemizedlist and compact spacing

Using:
- DocBook XML 4.2
- DocBook XSL Stylesheets 1.54.1
- Saxon 6.5.2

I want same of my <itemizedlist>s to appear in 'compact spacing'
and thus markup these <itemizedlist>s with an 'spacing="compact"'
attribute which gets transformed by the stylesheets to 
'<ul type="disc" compact>'.

But at least Mozilla makes no difference in displaying such HTML
compared to 'ul' w/o 'compact'.

Is there any way (e.g. CSS) to get the wanted rendering?

Michael
